there are only two fare buckets on these flights -
B for flexible economy - tier points and 1500 miles if gold
J for flexible Business - tier points still only 40 rt as single cabin on a UK Irish route but 2000 miles for gold
The plane is a Saab340 with only 34 seats, in a 1- 2 arrangement, in a single cabin - there is a picture on the loganair website.
Best seats are row 2 and 7
Do this run (LDY-DUB) at least once a week - it is the quickest and nearly cheapest way to my DUB office thanks to the Irish PSO
